JAMES E. SIMPSON, OF BROOKLYN, NEW YORK.

rinn-rnonncnve PEN.

Application filed June 30, 1916.

To all whom it may concern Be it known that I, James E. SiMrsoN, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Line-Producing Pens, of which the following is a specification.

This invention relates to line producing devices, for use by draftsmen, bookkeepers and others, and my improvements have particular reference to a novel form of pen, whose marking portion consists of a wheel or disk, having an ink supply, and a holder, and which is capable of being moved along a straight edge, or ruler, to produce a line.

In the drawing Figure 1 is a side view, partly in section, or" one form of my improved line producing device.

Fig. 2 is an enlarged, detail, sectional view thereof.

Fig. 3 is an end view.

Fig. 4 is a view of another form of my invention.

Fig. 5 is a perspective view of the device shown in Fig. i. I

Fig. 6 shows a blank used in producing a multiple line forming device, and

Fig. 7 is anend view of Fig.6.

In carrying out my invention, I employ a wheel or disk 1, having a narrow peripheral edge, which, when supplied with ink, and rolled along a surface, will leave the imprint of a drawn line thereon. Said wheel or disk may be journaled upon a shaft, as 2, which may be mounted, or secured, as by riveting, across a support 3. Said support is here shown as a tubular member, square in cross section, opposite walls thereof forming the bearings for the shaft or pivot. The wheel 1 protrudes beyond said walls, one of which serve as a. flat, straight bearing in the operation of the device. The other end portion of the tubular member may be circular in cross section, and its wall. provided with a spiral thread, pressed or otherwise formed therein, to securely receive a stick or holder l. The space within the tubular member lying between the wheel or disk and the stick end, may contain an ink pad, which may be of spherical or other shape, and of absorbent, ink carrying material. Said ink pad, inclicated by the numeral 5, bears against the Specification of Letters Patent.

peripheral edge 01 the wheel or disk 1,

whichit supplies with ink.

It will be noted, in Figs. 1, E2- and 3, that two wheels 1 are provided in the device, they being separated from each other by a central plate or wall 6, which also divides the rearward space between the wheels 1 and the stick 4:, so that the two compartments thus provided may contain separate ink pads 5 of difi'erent colors. By the means thus provided, the separate wheels may be caused to produce inks, as for example, one wheel producing a black line and the other a red line.

In the two wheel device each wheel is placed near to its outer wall, the longitudinal axes of said wheels being in parallelism with said walls, which thus act-as guides for the wheels in producing straight lines. A wheel with its guide wall being set near together permit the production of the line in proximity to the straight edge of the ruler employed. A slight inclination of the device, in ruling, tilts-the far wheel out of contact with the surface of the work sheet, thus allowing only the inner wheel to mark a line on said work sheet. A cap 7 may be used to cover and protect the wheels when not'in-use.

The modified device of Figs. 4 and 5 has one wheel 8, with ink pad 9, the walls 10 of this device being brought near together to leave just sufficient clearance between them to receive said wheel. Said walls are shown as inclined outwardly away from the flat, bearing portions thereof. forming a pocket between the end of stick 11 and the wheel, to contain the ink pad 9. Said ink pad may be attached to the stick, and thus emovable therewith, whereby said stick may be used as a handle for dipping the pad in an ink receptacle, to renew the supply. This form of the invention is particularly adaptable for use with india ink. A removable cap is shown at 13.

In the further modification of Figs. 6 and 7 means are provided for employing in the same pen wheels of diiierent widths for the production of lines of varying thickness. This may comprise a triangular shaped blank 14, having the lugs 15, which are bent at right angles to the blank to serve as bearings for the pivots 16 of the respective wheels 17, 18 and 19; said blank being inset in a triangular shaped form or mount lines in different colored 20, which may be tubular, and provided, similarly to the other forms of my invention, with inking means and a handle.

By the construction shown it Will'be observed that each wheel, 17, 18 and 19, has its own flat, parallel bearing wall for application to a straight edge ruler in producing lines, and that the thickness of the line roduced is determined by the selection of a particular wheel within the variable range of the group of wheels provided.

The separate wheels 17, 18 and 19 are employed individually by slightly tilting the mount in the direction of the particular wheel which is to produce the required line, the bearing wall for that wheel being guided by contact with a ruler or straight edge. This tilting action, communicated through holding the handle at an angle, is so slight as to not interiere with the marking ability of the wheel, although sutlicient to lift the other wheels out of contact with the work sheet.

Obviously the edge of each of the wheels may be arranged at a suitable inclination so as to allow parallel cont-act between said edge of the work sheet when the device is tilted for use.

The ink supply to the wheel or wheels,

in any of the forms of my invention as herein shown, may be conveniently regulated by moving the stick end into more or less close relation with the ink pad, as is obvious.

I claim 1. A line producing device comprising a wheel, inking means therefor, and a supporting handle, said handle having adjustable endwise bearing against said inking means, and serving to operatively position said ink ing means with relation to said wheel.

2. A line producing device comprising a wheel, a mount therefor, inking means for said wheel carried by said mount, and an operating handle adjustably fitting in said mount, having endwise bearing against said inking means, and said handle serving to operatively position said inking means with relation to said wheel.

3. A line producing device comprising a wheel, a hollow mount in which said wheel is journaled, said mount containing an inking pad for said wheel, and a handle fitted in said mount, and having endwise bearing against said pad, and said handle being adjustable in said mount to regulate the pressure of said inking pad against said wheel.

4:. A line producing device comprising a wheel, a mount therefor having a fiat external bearing surface parallel with the plane of said wheel, for its guidance along a ruling edge, inking means for said wheel, and an adjustable handle fitting in said mount, said handle abutting against said inking means to operatively and adjustably position the latter with relation to said wheel.

A line producing device comprising a plurality of wheels, whose peripheral edges are of different widths, a mount therefor having flat external bearing surfaces respectively for the guidance of said wheels individually along a ruling edge, said bearing surfaces forming the three sides of a triangle, an ink supply for said wheels, and an operating handle.

6. In a line producing device, in combination, a triangular shaped mount, a wheel revolubly supported within said mount at each side thereof respectively, each side of said mount having a flat external bearing surface, parallel with the plane of its wheel, for its guidance, a ruling edge, inking means for said wheels, contained ,within said mount, and a handle extending from said mount.

Signed in the borough of Brooklyn, in the county of Kings and State of New York, this 27th day of June, A. D. 1916.
